r 5 invention UNITED STATES HOWARD COlLED-WIRE BELT.

SPECIFICATION forming part of Letters Patent Application filed July 3t, 1882.

[O and this object I attain in the manner which I will now proceed to describe, reference being bad to the accompanying drawings, in which- Figure 1 is a view of a pair of pulleys connected by. a belt of the character to which my relates; Fig. 2, a view of the opposite ends of the belt constructed in accordance with my invention, and Fig. 3 a sectional view of the joint or coupling.

Coiled-wire belts such as shown in Fig.1

20 are advisable for many purposes in place of rubber belts or gearing; but difficulty has been experienced in properly connecting the ends of a belt of this class.

In carrying out my invention I provide a 25 ready means of effecting a firm and elastic connection of the opposlte ends of the belt. I make the wire coil of a length somewhat greater than that which is necessary for the belt, the diameter of the coil being reduced at 0 one end of the belt, as shown in Fig. 2, and

this reduced portion or being then thrust or screwed into the opposite end of said belt, as

shown in Fig. 3. By this means the ends of the belt are caused to take such a firm hold upon each other that the loosening of the belt 5 or the separation of the ends is effectually prevented. A prominent advantage of the connection is that it is flexible, so that it offers no resistance to the curving of the belt, as the latter adapts itself to the pulley.

I am aware that it has been proposed to connect the ends of leather belts by screwplugs adapted to nuts on the ends of the belt, or by a spring adapted directly to the ends of the belt; but the main feature of my invention 45 is the dispensing with the separate pieces which these methods of connection require, the connection in my improved belt being integral with said belt.

It is advisable in most cases to face one or 5; both of the pulleys with rubber, in order to insure a proper hold of the belt thereon.

I claim as my invention- A coiled-wire belt having the coils at one end reduced in diameter and introduced into the coils of the opposite end of the belt, as set forth.

In testimony whereof I have signed my name to this specification in the presenceot' two subscribing witnesses.
